Elastic Behaviour, Stress & Strain

The strain-stress plot for materials A,B,CA, B, C and DD is shown in the figure. Which material has the largest Young's modulus?

Show answer and solution

Answer: (d)

  1. Y=stressstrainY = \frac{\text{stress}}{\text{strain}}
  2. The graph has strain on the y-axis and stress on the x-axis, so slope =strainstress=1Y= \frac{\text{strain}}{\text{stress}} = \frac{1}{Y}.
  3. Largest YY means the smallest slope, which is line CC.
  4. So the answer is (d) CC.
